To all whom it may concern.'

- Be it known tirati-,ARTHUR JAMES MASK- i REY, a citizen of the United States of America, an resident of Chesten'county of Hancock,

an -Statev rof West' Virginia, have invented -certam "new and useful Improvements 1n Catchers for Metal "Plates, of which the fol-l 'lowing is -a specification.

This inventlonreiat'es to improvements 1n A1.0 catchers vfor metal plates, and more particu- 'larly to a new and useful tinand terne platev catcher and deliverer, and still more particularly to a machine for gras ing sheets of i In'etal as they rise from the ro ls of a tinning '-lf ot and for delivering said .sheets toguides eading to a brauner.

The prim'ary object of the invention is,to provide a mechanical catcher of the-charaef lter above referred to, which is adapted for Specification. of Letters Patent.

Referring to said drawings, in which like designating characters distinguish like parts throughout the several views-1 indicates the ordinary tinning pot, on the opposite ends of which .is secured in any vsuitable manner, preferably by bolts 2, a small hous ing 3 provided at opposite sides thereof-.with

rectangular openings 4, inv which is mounted,

as is clearly shown in Figs.' l, 2, 8 and 9,' bearl .7.0

A furtherobject ofthe invention isto prof videa mechanical device for' catching metal y. rsheets which is adjustable to meet the `requirements of diereut sized sheets and .30 which is also adjustableto regulate the gri or pressure alpplied tothe sheets, and whic is further se f-regulatiu thus allowing? for the gripping offplates of iiferent thicknesses. further object isV to vprovide a the edges thereof and which wil 'lar e ease spots thereon.

ii these and other objects `in view, all

of which will hereinafter be made apparent,

not leave '40 the invention finally consists in the particular construction, arrangement and comblnavtion of parts which hereinafter be fully '.describeghreference being herein had tothe accompanying drawings, forming a partof 45 this spe'ciiicatiomdn which- Figure -1. is a top plan view of the invenj tion, the-same being shown mounted in place over a jumbo tinning 4pot; Fig. 2 is an end elevation ofthe saine; Fig. 3 vis au enlarged side elevation' of a posed disks, one of W 'cli is shown partly. in Ts'eetion'; Fig. 4 .is a crossfsection ofv a' disk withthe teeth removed; Fig. 5 is a side ele- .vation of a detached tooth; Fig. 6 is a t'op plurality of radially-disposed sockets l12 in;

each of which is seated aspiral spring 13, the f 5 ward and meeting, tlience spreading a art so througrwhich an adjusting-screw lllis rojected into impingin Irelation Wiihthe's Jfor holding saidv dis in adjustedposition. .Each disk is provided with acirc'ular annular ehannel 11 therein, and in 4said. channel isa outer-end of which abuts against the iiat 1in- .v der face 14 of a toothl which is mounted, substantially as shown, upona pivot 16.-

17; the iront face' 18 of which is'inclined substantially as shown in relation toits said `face 14, and terminates in a rounded point 19 90 y adapted for engaging'the metal plate, and .a rearwardly an -mwardly extending lug or tail-,piece 20 whereby the tooth is prevented mediate said body and tail-piece, as shown.

"Pivoted on the-shaft 6 is a guide-arin 22, clearly shownin Fig. '7, and on-the op osito 'f shaft 7. is pivoted a guide-arm 23, the ower ends or mein bers 24 and 25 of said guides be ingsimilarly shaped and extending downas to straddle thepointfofcontact of t e discharge-rolls 26 of the' tinning pot. The guide-'arm 22 is rovided above its pivotal connection witht e shaft with a curved .forwardlymclined arm-27 which' is adapted-t0.-

incline the metal sheets forward as .they rise.

`Said guidearm 22 is so formed and its weight Each of said teeth consists of a body portion sai is so distributed that it normally stands balanced upon the shaft 6 with its guide-member 24 in opposingrelation to the similarly shapedmem er 25of theguide-arm 23, the latter-arm being -provided with a balance- Weight 28 whichis ada ted to normally hold member 25 thrust orward, as shown. Mounted on th; edge of the ot l are u rights 2t sup orting anA inc ined doub e ychute 30, saidjc ute being composed of a plurality of parallel bars 31, upon which `the sheets of metal fall as they are passed `up- Ward by the disks. At each side of the chute is provided a side-guide 32, and intermediate said guides is', a central lguide 33 which divides the respective ends of said chute'. The

upper ends ofA said inclined parallel bars 31 are curved andoverlie ithe shaft 7 in osition to receive a sheet passed upward etween the teeth of the disks. The lower end of said chute 30 is suitably mounted for directing sheets therefrom to suitable tables 34 ar- 'y 'ran ed for discharging said sheets to a guide lea Ing to the brauner,

The bearing-blocks 5 are fitted inthe rectangular openings 4 of the housing 3 so that they will haveconsiderable play, as is clearly illustrated in Figs. 8 and '9, and a horizontally directed adjusting-screw 35 i's4 rovided through the housing 3 whereby sai blocks, bearing the shafts, may be adjusted with relation to each other, means bein thus ro.-

-vided whereby the pressure of t e teelty of 'the disks upon the sheets may be regulated. 35 into the un er side of each bearin -block is an adjusting-screw 36, whereb 'Extend' upward throug the housing-3 t e shafts may be raised` or loweredA to a apt the machine to sheets of metal of different lengths.

A driving shaft v37 is suitabl7 mounted at one end of the `tinning pot, sai shaft having fixed thereon' a drive-wheel 3 8 and avge'ar- Wheel 39, the latter beingr in meshing engagement with aV gear-wheel 40 on the shaft ot, and, as it rises, is

6.4 At the opposlte end of the machine, a gear-Wheel 41 1s mounted on the shaft 6, said gear-Wheel meshing with a similar Vgear- Wheel 42 mounted on the shaft 7.

The operation of the invention is substan.

tially as follows: The metal sheet 43rises between' theA discharge rolls 26 of the tinning asped by the opposing-teeth 15 of the dis 8, which disks are .lp geared so lthat theirA eripheral sp'ccdis the A same` as that of the ro ls 26, and is carriedu ward by said teeth as said disks revolve, t 1e. upper ed e thereof engaging the inclined arm- 27 by W `ch it -is thrown forward so that; when `thewhole sheet has passed fronibetween -the teeth it will fall upon the bars 131 .of the chute 30. Directed by the guides 32 and 33, said sheet slides, forward the tafA As is apparentfrom the fore oing, Ifprolvide an extremely simple and e cient device for the purposes specified, and, since the bearing surface of the teeth upon the sheet is very limited in extent, thelatter is but little liable to be injured or marred by contact with said teeth. lThe present construction overcomes the objection to a plain disk,

4 which objection lies in the fact that such plain disks smudge the sheets with grease or palm-oil from the pot.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
